B0501Passenger Power Window Circuit Malfunction
- Generic OBD-II code · Body
- How the car detects it
- For B0501 neither the reachable J2012 lists nor any manufacturer offer a definition, so the code is unverified. The title points to the front passenger window circuit. Saab's 9-3 passenger door module uses B3205/B3210 for its own motor paths and B3932 when it measures current while the motor should be idle; one-touch travel then stops. GM's 2011 9-4X sets B3210 for the passenger motor if its compatibility code does not match the BCM. Honda's US7145299B2 shows the classic layout in which the driver's master switch commands the passenger door over a single line, so the fault may sit in the master switch, the line or the local switch. Without working reversal, FMVSS 118's 100 N limit rules out automatic closing. The passenger switch circuit is B0247.
